A compound for use in the treatment, profylaxis or diagnosis of bacterial infections caused by pneumococci, having the general formula:
wherein R' and R2 independently are hydrogen or carbohydrate residue and R3 is hydrogen, lower alkyl or a carbohydrate residue, whereby R3 may constitute the residue of a natural or synthetic glycoconjugate, and whereiun R4 is hydrogen and R. is acetyl or R4 and R5 together with the nitrogen atom to which they are attached form a cyclic imide, whereby R1 is other than a galactose residue or derivative thereof;
compositions containing such compounds; process for identification and quantification of such compounds; process for purification of acceptor structures of bacteria; process for determining the presence of pneumococci in samples from living animals; and new carbohydrate compounds.
